The short version

  • Only Calm has a free tier, so it costs nothing to try first.
  • Each has a real cost: Calm free tier is severely limited, with almost all content requiring payment; Rad AI the products are not FDA cleared devices and are not intended to be, so any claim that Rad AI improves diagnostic accuracy is unsupported; what has been measured is reporting speed and follow-up completion, not detection.
  • They diverge on capability: Calm covers Sleep Stories, Rad AI covers Impressions.
  • Prices and features above were last checked on 1 September 2026.

  • Fitness coachingnot Rad AI
  • Wellness improvementnot Rad AI

Rad AI

  • A private radiology practice whose read volume has grown faster than it can recruit and that wants dictation time per study reduced without changing PACSnot Calm
  • A health system losing revenue and exposing itself to liability because recommended follow-up imaging on incidental findings is never bookednot Calm
  • A radiology department standardising impression quality across a mixed group of employed and locum radiologistsnot Calm
  • A group deploying an AI tool that must not trigger a device validation programme, because governance capacity is already consumed by a triage algorithm rolloutnot Calm

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Calm

  • Free tier is severely limited, with almost all content requiring payment
  • Only one meditation per day included in free tier (Daily Calm)
  • Annual pricing is among the highest in the meditation app category
  • Less extensive free content library compared to Insight Timer (which has 100,000+ free meditations)
  • Limited customization of meditation sessions; mostly follows Calm's curated content

Rad AI

  • The products are not FDA cleared devices and are not intended to be, so any claim that Rad AI improves diagnostic accuracy is unsupported; what has been measured is reporting speed and follow-up completion, not detection.
  • Generated impressions require radiologist review and signature, so the time saving evaporates in any group whose radiologists rewrite the draft rather than edit it, and adoption varies sharply by individual.
  • It is bound to your dictation platform, so a group planning to move off PowerScribe should sequence that decision first or expect to redo the Rad AI integration.
  • Continuity depends on the quality of recommendation language in historical reports, and departments with inconsistent phrasing get poor recall until reporting practice is standardised.
  • Pricing is not published and is structured per radiologist or per study depending on the product mix, which makes it hard to compare against image-analysis AI vendors that price per scan.

Answered from the vendors’ own pages

Calm: What does Calm's free tier include?

The free plan includes 1 breathing exercise, Day 1 of programs, select Sleep Stories, and Scenes, plus the famous Daily Calm feature and bedtime stories. Most content is locked behind the paid tier.

Source
Rad AI: Is Rad AI FDA cleared?

No, and by design. The products draft text and manage follow-up workflow rather than interpreting images, so they fall outside the device pathway. Treat any diagnostic accuracy claim with scepticism.

Calm: What is included in Calm Premium?

Calm Premium (all paid tiers are identical) includes The Daily Calm, Sleep Stories narrated by celebrities, exclusive music playlists, masterclasses taught by experts, Daily Move video lessons for stretching and mindful movement, and the entire content library.

Source
Rad AI: Does the radiologist still sign the report?

Yes. Output is a draft that the radiologist reviews and signs; nothing is released autonomously.

Calm: How much does Calm Premium cost?

Monthly subscription is $12.99/month, annual is $69.99-$79.99/year, Family Plan is $99.99/year (includes 1 Admin + 5 Members), and lifetime membership is available as a one-time payment.

Source
Rad AI: Which product actually pays for itself?

Continuity has the clearest financial case, because recommended follow-up imaging that gets completed is billable work that currently does not happen.

Calm: Does Calm offer pricing for organizations or teams?

Yes. Calm offers organizational plans for groups of 5-300 people with per-seat pricing based on total 'covered lives.' Larger groups receive deeper discounts. Pricing is significantly reduced compared to individual subscriptions.

Source
Rad AI: Will it work with our dictation system?

It is deepest with Nuance PowerScribe. Confirm your specific dictation and PACS combination before contracting, because integration depth is the main deployment variable.

Calm: Does Calm work offline?

Calm's app functions offline for already-downloaded content. Downloaded Sleep Stories, meditations, and Music programs can be accessed without an internet connection.
